That's because people complained that there was already a long-standing routine
in the IDL Astronomy Library called strsplit, so RSI renamed it strtok.
However, because they had already advertised that they were adding strsplit,
they provided this wrapper. Now people are complaining about strtok. I guess
you just can't win. ;^)

It's even more irritatingly trivial than that. They added strtok, then
decided to call it strsplit, but instead of renaming it they wrote strsplit
as a wrapper. Strsplit's code, in its entirety, is:
function strsplit, string, pattern, _ref_extra=extra
if (n_params() eq 1) then return, strtok(string, _extra=extra) $
else return, strtok(string, pattern, _extra=extra)
end
I hope RSI doesn't sue me for violating copyright by reproducing this. Think
of the advantage their competitors could gain by perusing it!
P.S. No more frivolous posts for a week, I promise!

Randall Smith (rsmith@kracko.harvard.edu) makes a good point
when he writes:

In a perfect world, of course, all software programs would
be written with the end result clearly in mind. This is how
all of *my* programs are written. :^)
